Why Sweat and Body Odor Care Is Essential During Summer in Japan
Japan’s summer is known not only for its high temperatures but also for its high humidity.
As a result, people tend to sweat more than in many other countries.
The underarms are especially prone to sweating because they contain a high concentration of sweat glands.
However, body odor is not caused by sweat itself.
It develops when bacteria feed on sweat and excess oil on the skin.
That’s why in Japan, effective sweat care focuses on two things:
- Reducing perspiration
- Preventing the growth of odor-causing bacteria
Both are considered essential for staying fresh during the hot and humid summer months.
Because people are often in close contact with others on trains, elevators, and in meeting rooms, many Japanese people consider deodorant and antiperspirant products part of everyday etiquette.
Antiperspirant vs. Deodorant: What’s the Difference?
Although these products are often used together, they serve different purposes.
Antiperspirants
- Help reduce the amount of sweat
- Contain active ingredients that help control perspiration
Deodorants
- Help prevent body odor
- Contain antibacterial and deodorizing ingredients that target odor-causing bacteria
Today, many Japanese deodorants combine both antiperspirant and deodorant benefits in a single product.
Men’s and Women’s Deodorants
There is very little difference in effectiveness between men’s and women’s deodorants in Japan.
The main differences are:
- Fragrance
- Packaging
- Cooling sensation
Men’s products often contain menthol for a stronger cooling effect, while women’s products usually feature gentle scents such as soap or floral fragrances.

Body Wipes Are Also a Summer Essential in Japan
One unique feature of Japanese summer sweat care is the popularity of body wipes.
In Japan, many people carry body wipes in their bags during summer.
They’re commonly used after commuting, exercising, or spending time outdoors—especially when taking a shower isn’t possible.
Body wipes quickly remove sweat, excess oil, and the bacteria that can cause body odor, leaving the skin feeling clean and refreshed.
Many varieties are available, including cooling wipes with menthol, moisturizing formulas, and fragrance-free options.
How to Choose Body Wipes
Cooling Effect
- For an intense cooling sensation: choose wipes with menthol or peppermint oil.
- For sensitive skin: choose a mild cooling formula.
Sheet Size
- Large, thick sheets: ideal for wiping the whole body.
- Compact packs: perfect for carrying on the go.
Fragrance
Popular options include:
- Fragrance-free
- Soap scent
- Citrus
- Floral
If you have sensitive skin, alcohol-free or low-irritation formulas are recommended.
